IMPROVEMENT IN HORSE-POWERS OR DERRICKS FOR DRILLING WELLS.

Specification forming part of Letters Patent No. 171,840, dated January 4, 1876; application tiled'-l November 13, 1875.

tion of the saine, taken through the line m a', Fig. l. Fig. 3 is a horizontal section of the same, taken through the line yy, Fig. 1.. Fig. 4 is a horizontal section of the same, showing the auger cross head or bar in place. Similar letters of reference indicate corresponding parts. l The object of this invention is to furnish an improved hollow revolving horse-power or derrick for sinking wells, which shall be so constructed as to operate the auger, and raise it without stopping the horse or changing his direction, operate and rotate a drill, and guide the tube and hammer when sinking a drive- Well, and which shall be simple in construction and convenient in use.

The invention consists in the combination of the stationary anged ring` and the revolving grooved ring with the base-frame, the posts, and the sweeps; in the combination of the cross-bar, to which the hoisting rope or chain is attached, and provided with rollers upon its ends, with the rabbeted or shouldered posts ofthe revolving` hollow horse-power; in the combination of the upright shaft and its gear-wheel with the posts, the grooved ring, and the teeth of the stationary ring, to drive the operating parts by the revolution of the said ringand posts; and in the combination of the cam-wheel and the pivoted lever with the upright shaft and the revolving ring, as hereinafter fully described.

A is the base-frame of the machine, to which is securely bolted a cast ring, B, having gear- 'teeth formed upon its outer or convex side,

and an inwardly-projecting liange formed upon the lower part of its inner or concave side. C is aring-casting, having a rin g-groove formed upon its lower side, of such a size as to receive the ring B, and of such a depth that the inner part of said casting may rest and turn upon the flange o f the casting B. Upon the opposite sides ofthe top of the ring O are formed two sockets, c', to receive the lower ends of the uprights or posts D, the upper ends of which are connected by a cross-beam, E. To the center of the beam E is attached a pulley, G, to receive the hoisting rope or chain, and to the top of said beam is swiveled a spider, H, to receive the guy ropes or chains, for adjusting and securing the machine in a vertical position. Upon the upper part of the outer side ot' the ring C, a little in front of one of the post-sockets c1, is formed a bracket, c2, to receive, and serve as a bearing to, ,the lower part of an upright shaft, I, to the lower end of which is attached a gear-wheel, J, the inner side of which. projects through an opening in the outer part of the ring O, and meshes intothe teeth of the ring B. rIhe upper part of the shaft I revolves in bearings in a bracket, K, attached to one of the posts I), and to its upper end is attached a bevel-gear wheel,

"L, the teeth of which mesh into the teeth of a bevel-gear wheel, M, attached to a shaft, N. The shaft N revolves in bearings in brackets K, attached to the posts D, and is made with long bearings, so that it may have a longitudinal movement, to throw the gear-wheel M into and out of gear with the gear-wheel L. To the shaft N is attached a drum, O, to receive the rope or chain for raising and lowering the auger, drill, or hammer. Around a pulley, P, attached to the shaft N, and which may be :formed by turning down the end of the drum O, is passed a strap, Q, one end of which is secured to the bracket K; and with its other end is connected the end of the lever R, pivoted to the said 'bracket K, so that when the auger or drill is allowed to run down by its own weight its rapidity of descent may be readily controlled. The shaft N is moved to throw the gear-Wheel M into and out of gear with the gear-wheel L by the lever S, which is pivoted to the bracket K, and the forked end of which rides in a ring-groove in the hub of the gear-wheel M. The lever S is locked in either position by a'catch-bar, T, attached to the post D. The end of the shaft N is squared after each blow.

off to receive a crank, to enable theauger to be prevented from entering the ground too rapidly. "The forward parts of theinnersides of the posts D are rabbeted, to form shoulders for the inner ends of the cross-bar orcross-` head Uto rest against, which ends have small rollershuypivoted to them. The cross-bar U is attached to the endof, the hoisting rope or chain, and hasfthe upper end of the auger-I shaftconnected with it by lugs and a key or otherconvenient means. With this construction the revolution ofthe machine, by pressing against the ends of the cross-bar U, forces the auger into the ground. Vis a stud,attached to the ring-casting C, near the base of the bracket c2; and in a slot in its upper end is pivoted a lever, W. The inner end ot' the lever W projects, so asi to be directly over the centerot' the ring C, and with it is designed to be connected the drill. .The outer end of thelever W projects toward and nearly to the shaftI, and `has a small roller` w', attached to `it to diminish friction.

` To the shaft I is attached a wheel, X, which has one or more calnsibrmedupon its lower side, to bear upon `the outer, end ofthe lever W, to raise the drill and allow it to drop to give the blow, the revolution of the hollowpower turning the drill The horses to operate the l powerare attached to the sweeps Y, the inner ends of' which are bolted to thering G or sock- ,ets cl, and which are strengthened against the Hdraftstrain by braces Z. The posts D are secured in an 'upright position by the braces Z2. The lower ends of the braces Zl Z2 are' secured lugs`c3, for1ned upon chewing-casting C.

When the power is used for sinking drivewells, strips dare secured lin .the `rabbetsot -thc posts D, to `form guidegrojoves to receive the ends ot' a cross-bar, for centering'the tube and keeping it in a vertical position, and "to form guide grooves or ways for the hammer.

Having thus described my invention, I claim as new and desire to secure by `Letters Patent- 1. The combination off the stationary flanged ring B and the revolving grooycd ring() with the baseframe A, the posts D,Va.nd the sweeps Y, substantially as herein shown and described.

2. The combination of the cross-bar U, to which the hoisting rope or `chain is attached, and provided with rollers-ul upon its ends, with the rabheted or shouldered posts ot the revolving -hollow horse-power B C D, substantially as herein shown and described.

3. rlhe combination of ,the shaft'I andthe geanwheel J with the `posts iD, the grooved ring C, and the teethofthelstationary ringfB, substantially as herein shown and described, to drive the operating parts by therevolution of the ring C and postsD, as set forth. `l`

4.. The combination of the cam-wheel X and the pivoted lever W with the shaft I and the revolving rin gG, substantially as herein shown and described. i
